摘要：

Polybetaines with narrow molecular mass distribution (M(w)/M(n) < 1.25) are synthesised directly for the first time; group-transfer polymerisation of 2-(dimethylamino)ethyl methacrylate (DMAEMA) yields near-monodisperse precursor polymers which are quantitatively betainised under unusually mild conditions using 1,3-propanesultone; block copolymerisation of DMAEMA with alkyl methacrylate comonomers, followed by betainisation, leads to hydrophilic-hydrophobic sulfopropylbetaine block copolymers.
